Purpose: To teach facility managers the benefits of upgrading to a high SEER air conditioner for a more efficient building.


  • What is SEER?
  • How does a high SEER impact my energy bills?
  • What rebates will my business get for upgrading my AC?
  • How does a high SEER impact the environment?

If your air conditioning system has been working fine for many years now, then you can consider yourself fortunate for having equipment that is proving to be quite durable.

However, for all the toughness that your AC unit has shown over the years with the help of proper maintenance and air conditioning service, nobody can deny the fact that your old air conditioner uses up a lot of electricity to help make your place of business more comfortable. The result, of course, is a high energy bill every month, no thanks to the fact that your existing AC unit has a low SEER like all other older air conditioning units.

What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio, which measures air conditioning and heat pump cooling efficiency.  Generally, the higher the SEER, the more energy-efficient it is.

Considering how manufacturers have taken great strides in increasing the efficiency of air conditioners and heat pumps over the last 10 years, it only makes sense to seriously consider updating your AC unit to a higher SEER as it brings with it a number of benefits that are hard to ignore. Let’s take a closer look at some of the great things about getting new, high SEER AC unit.

Energy savings

Since high SEER AC unit uses less energy, you can expect a lower utility bill at the end of the month. The savings, of course, will depend on the SEERs of your old and new units. Let’s say your old unit had an 8 SEER, and your new air conditioner has a SEER of 16. That means your AC’s electricity use will be cut in half, and that will be reflected in your next utility bill.

Imagine your energy savings if you get a unit with a SEER of 20 or more.

Improved moisture removal

One of the indicators of an AC unit’s effectiveness is its ability to remove moisture from the air. High SEER units are particularly effective at moisture removal because they cycle longer at lower pressures. With longer cooling cycles, there would be fewer opportunities for mold and other humidity-related issues to take hold because moisture is effectively removed from the air.


High SEER AC units are more energy-efficient, and that means having one installed in your home or your place of business helps you reduce your carbon footprint, which the environment will surely appreciate. Aside from having a higher SEER, most new air conditioners also use safer refrigerants, making the installation of a new, high SEER AC unit one of the more eco-friendly things you can do.


Government and private sector rebates and incentives

One thing you need to know about newer, high SEER AC units is that they have much higher price tags than your old system. However, your investment will go a long way and will save you money in the long run.

Aside from the energy savings you will get from these more energy-efficient units, you are also poised to enjoy rebates and incentives that government agencies and the private sector offer those who use more efficient equipment and therefore use less energy. Federal, state, or local governments and utility firms typically offer direct rebates, or tax credits or deductions to people with reduced energy consumption.


Future buyers will go for a high SEER system

In a world where people are becoming more conscious about helping the environment, a high SEER AC unit in your building can become a unique selling point when the time comes for you to sell it. Your efficient air conditioning unit will definitely attract more potential buyers, and may even help you fetch a better price.

There is great value in replacing your old AC unit with a new one because of the higher SEER ratings, which have increased gradually in recent years. The fact that entry-level models of newly-manufactured air conditioners are now much more efficient than standard models of older units should be enough reason for you to update your AC unit.

Remember, however, that the SEER is only one factor in determining how energy-efficient your AC use can get in general. Proper installation of your AC system is a crucial factor, and so is its maintenance. The same can be said about right-sizing the AC system for maximum efficiency. Consult with a reputable HVAC contractor to help you make your AC system as efficient as it can get.
